  • Patent number: 11519138
    Abstract: A soil processing machine includes a machine frame with two longitudinal beams substantially extending in the longitudinal direction of the machine and two transverse beams substantially extending transverse to the longitudinal beams. A soil-processing roller is supported in the longitudinal direction between the transverse beams on the longitudinal beams so that it can rotate about an axis of rotation of the roller. A coupling arrangement is provided on the machine frame for attaching the machine frame to a further machine frame of the soil-processing machine or to a further machine. A lifting/supporting arrangement is provided on the machine frame for lifting and/or supporting the machine frame in relation to the ground. One of the transverse beams is supported on the two longitudinal beams so that it can rotate about a swivel axis substantially parallel to an axis of rotation of the roller.

  • Patent number: 11459711
    Abstract: A soil processing machine includes a machine frame having two longitudinal members positioned parallel to a machine longitudinal direction and spaced from each other transversely to the machine longitudinal direction, and two transverse members positioned extending transversely to the machine longitudinal direction and spaced from each other in the machine longitudinal direction. A soil processing roller is supported on the longitudinal members such as to be rotatable about a roller rotational axis and positioned between the transverse members in the machine longitudinal direction. A coupling assembly couples the machine frame to another machine frame of the soil processing machine or to another machine. A chassis assembly includes at least one height-adjustable chassis unit supported on the machine frame.
